Benefits of technology
The present invention is about a device and method for wireless charging in a vehicle that reduces interference with other electronic devices. The device is designed to work with existing wireless power transmission systems and can even avoid interference with smart keys used in vehicles.
Problems solved by technology
However, since the portable electronic device operates by consuming power stored in a battery cell (for example, a primary battery, a secondary battery, and the like), the battery cell needs to be charged or replaced in order to continuously operate the portable electronic device.
Since the terminal is exposed outside, the fire may occur when the foreign material is filed in the terminal, and there are problems in that the battery due to moisture is naturally discharged and the lifespan and the performance of the battery are deteriorated.
Accordingly, when the magnetic induced type wireless power transmission system is constructed in the vehicle, the interference between the operation frequency of the wireless power transmission system and the operation frequency controlling the corresponding vehicle may occur.
This causes malfunction of the wireless power transmission system and the vehicle.
When the vehicle is malfunctioned, a large accident may occur.

Abstract
A wireless power transmission device for a vehicle and a wireless charging method are provided. The wireless charging method by the wireless power transmission device for a vehicle can comprise the steps of: transmitting a signal for detection of a wireless power reception device by using a lower frequency band than an operating frequency band used to control the vehicle; receiving a response signal for the transmitted signal and a power control signal from the wireless power reception device; controlling an operating frequency and / or a voltage in the wireless power transmission device for the vehicle according to the power control signal; and transmitting wireless power to the wireless power reception device.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a national stage of International Application No. PCT / KR2014 / 009186, filed Sep. 30, 2014, which claims the benefit of priority to U.S. Provisional Application No. 61 / 885,522, filed Oct. 2, 2013, in the U.S. Patent and Trademark Office, the disclosures of which are incorporated herein by reference.BACKGROUND OF THE INVENTIONField of the Invention[0002]The present invention relates to a wireless power transmission device mounted on a vehicle and a wireless charging method.Related Art[0003]Recently, propagation of portable electronic devices including a smart phone, a laptop, a MP3 (MPEG-1 audio Layer-3) player, a headset, and the like has been spread. However, since the portable electronic device operates by consuming power stored in a battery cell (for example, a primary battery, a secondary battery, and the like), the battery cell needs to be charged or replaced in order to continuously operate the portable electronic ...
